Sounds crazy, but jackpot winners on MM and PB almost always have a number, sometimes two, that repeat from the last jackpot win. They also frequently each repeat jackpot winner numbers from one another:

Actually when numbers in combinations are profiled by letters according to the last time they were drawn, their profile will indicate the number of times a number repeated from which drawings. All the profiles that have an "A" or "AA" have one or two numbers from the previous drawing. All profiles that start with a "B" or higher have no numbers from the previous drawing. Different lotteries have different repeat rates depending on the amount of numbers in its field.

Here's another one that's difficult to use, but maybe someone will find it worth the trouble. It's an eliminator, as opposed to a means of identifying winners.

Some numbers have never hit in the entire history of 5+1 when various other numbers were bonus ball or red ball. Most bonus or redball numbers have a selection of these. Here's 37 as an example, the entire history of 5+1 in the US:

Once I've decided to use a particular number as a bonus ball I never run numbers with it that have never hit with it in the past, or that have hit so seldom in comparison with others as to make running them together an exercise in futility.

For the jackpot-style lottery games that I play I have a little PERL script that spits out each of the last 20+ drawings in order with some stats on the same line to the left of the numbers, then I have an RNG that spits out ten picks and what their statistics would be if they were The One™. I do some eyeball comparisons and pick the draws that I think look right. Mostly I compare the balls in a drawing to the balls that came up in drawings before it and count the matches.

I should mention that the RNG picks my scripts select have to pass through some filters. One thing I always filter out is any three or more ball combination that has come up in the last few months. While it is common for one or a pair of balls to repeat from previous drawings, repeats with three+ball combos tend to be more rare in lotteries with five or six balls.

The reason I use an RNG for my picks is because one characteristic that winning numbers have is randomness! After the drawing I check out the old RNG picks using the new results. I will keep playing an old pick until I get a drawing that matches at least three numbers, then I junk it.

All of these is very interesting, if I was a programmer I would also try to use a RNG in a similar way or ways to see how it would do for me.

Jap's stuff also looks like something that I should learn to do.

RJOH's stuff is easy enough to learn and to try.

as to Greg's stuff, I don't understand too well, maybe if he gave some examples (?).

As to Jack's stuff it looks very very interesting, but I don't understand it, some stuff is hard for me to understand, maybe I am too caught-up on my own ways to understand that, or I am just a dummie or both.

Thank you everybody, maybe there will be more ideas (?).

So far I like all the ideas given.

Take the pick 3, it is not very likely that all digits will be just cold or hot, maybe more often than not they are a mix of both, Does anybody know for sure ?

As to digit skips, what are the regular skips of the digit or the most common skips for them ? I is there a regular pattern there ?

Same with pairs, is there a more or less regular pattern for pair's skips ?

And what about boxed (any-order) and straight whole 3 digit numbers, is there a more or less regular pattern for many or most of their skips ?

And what about sums, sums' roots and last digit sums' roots, do they have more or less regular skip's patterns for many or for some of them ?

What about high-low and even-odd are there more or less regular skip patterns for some or many of them ?

What about width of digits and width of numbers, How do the skip patterns for them look ? Do they look more or less regular ?

What about other filter's pattern's, How do their skips look ? Any regularity to them ?
